Abstract：
Three pile testing programs, for different length of pile,different pile bearing layers and the status of rock-socketed piles,are designed,aim at three significant different medium weathered siltstone pile bearing layers on a construction site in Hangｚhou. In the construction of six test pile in different bearing layers, we developed a strong operational control standards judging from some key aspects like the judgments of rock embedding interface and rock samples,speed of drill pipe and total time of rock embedding. Based on the actual operation of the project,the pile safety,construction schedule,cost and management are scientific and rational.
